I had the same issue while installing Firebase in Xcode 15 and CocoaPods 1.12.1. Earlier CocoaPods version was working fine in Xcode 14.

So updating the CocoaPods version, and clearing the caches (optional) should solve this problem. Follow these steps:

Update CocoaPods

sudo gem update cocoapods

Reinstall dependencies via CocoaPods

pod install

Clean build in Xcode with command

Shift-Command-K

Run your target

It is an issue due to the old CocoaPods version with Xcode 15. This is resolved in the CocoaPods version 1.15.2.

Please make sure to remember the following steps.

Remove Any Existing CocoaPods Installation To prevent conflicts, let's start by cleaning up any existing installations of CocoaPods:

sudo gem uninstall cocoapods
brew uninstall cocoapods

Ensure Homebrew and rbenv are Set Up Correctly Confirm that you have Homebrew and rbenv installed correctly. If not, you can install or update them using the commands below:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
brew install rbenv ruby-build

After installing rbenv, add it to your shell:

echo 'eval "$(rbenv init -)"' >> ~/.zshrc  # or ~/.bash_profile for bash
source ~/.zshrc  # or source ~/.bash_profile

Install the Correct Ruby Version Make sure you're using the correct Ruby version for your environment:

rbenv install 3.3.3  # or your preferred version
rbenv global 3.3.3

Install CocoaPods Using gem Now, let's install CocoaPods using gem:

gem install cocoapods

Ensure that pod is in your PATH:

rbenv rehash

Verify Installation Check if CocoaPods is installed correctly:

pod --version

Edit Podfile and add them

  post_install do |installer|
  installer.pods_project.targets.each do |target|
    flutter_additional_ios_build_settings(target)
    target.build_configurations.each do |config|
      config.build_settings['EXCLUDED_ARCHS[sdk=iphonesimulator*]'] = 'arm64'
    end
  end
end

Install Pods in Your iOS Project Navigate to your iOS directory and install the pods:

cd /path/to/your/flutter/project/ios
pod install

flutter clean flutter pub get cd ios pod install flutter run

Do not try complex bypasses. You can just update cocoapods and it works fine. I have updated cocoapods to 1.15.2 from 1.12.1. Now issue is fixed automatically.

You can check your cocoapods version using pod --version. You can update it to latest using brew upgrade cocoapods.

For newbie IOS developer like me.

Go to Find -> Find and Replace in workspace

Press Replace ALL and then

IMPORTANT: Do not forget to save using CMD + S

Then clean the build.

Product -> Clean Build Folder and click run

For me work update cocoapods, which fix problem with xCode 15.

Upgrade Cocoapods v1.13.0.

Brew command:

brew upgrade cocoapods

Without Brew:

sudo gem install cocoapods

Then run in your project/ios folder

pod install --repo-update

Note: If you can just migrate to package manager. Especially when you starting new project.

Cocoapads needs to be updated for Xcode 15 to work. Go to terminal => your project => cd ios => sudo gem install cocoapods

Now go to Xcode -> Runner -> build Settings -> Check DT_TOOLCHAIN_DIR is replaced with TOOLCHAIN_DIR.If it is replaced, then it will work

When I tried to run a project whose pod is set up using Xcode 14.3 in Xcode 15.0, I faced the DT_TOOLCHAIN_DIR error. I solved it by the following:

I first removed the CocoaPods from the project and followed How to remove CocoaPods from a project?:
Cleared the DerievedData

I have written the below script at the end of podfile:

post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '13.0'
      xcconfig_path = config.base_configuration_reference.real_path
      xcconfig = File.read(xcconfig_path)
      xcconfig_mod = xcconfig.gsub(/DT_TOOLCHAIN_DIR/, "TOOLCHAIN_DIR")
      File.open(xcconfig_path, "w") { |file| file << xcconfig_mod }
    end
  end
end

then used pod install.

This fixed my problem.

Similarly, in order to run the project whose pod is set up using Xcode 15.0 in Xcode 14.3, I used the below approach:

First removed CocoaPods from the project. I followed How to remove CocoaPods from a project?
Cleared the DerievedData
and ran sudo gem update xcodeproj
then used pod install.

Note: You can use pod cache clean --all before pod install

Navigate to and open with sudo with nano, sudo nano. Paste the path:

/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS17.0.sdk/System/Library/Frameworks/WebKit.framework/Headers/WKWebsiteDataStore.h

Search for: __IPHONE_OS_VERSION_MAX_ALLOWED. Change it from 170000 to 180000.

Navigate to your pod file. Comment as commented below:

  # installer.generated_projects.each do |project|
  #   project.targets.each do |target|
  #     target.build_configurations.each do |config|
  #         config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '12.0'
  #       end
  #   end
  # end

Then add this:

installer.pods_project.targets.each do |target|
  target.build_configurations.each do |config|
      if Gem::Version.new(config.build_settings['IPHONEOS_DEPLOYMENT_TARGET']) < Gem::Version.new('13.0')
        config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '13.0'
      end
    end
    flutter_additional_ios_build_settings(target)
    target.build_configurations.each do |config|
    xcconfig_path = config.base_configuration_reference.real_path
    xcconfig = File.read(xcconfig_path)
    xcconfig_mod = xcconfig.gsub(/DT_TOOLCHAIN_DIR/, "TOOLCHAIN_DIR")
    File.open(xcconfig_path, "w") { |file| file << xcconfig_mod }
    end
  end
end

For non-Flutter, or I should say for people code use native Swift in their projects. Adding the following snippet in my Podfile fixed it for me.

post_install do |installer|
    xcode_base_version = `xcodebuild -version | grep 'Xcode' | awk '{print $2}' | cut -d . -f 1`

    installer.pods_project.targets.each do |target|
        target.build_configurations.each do |config|
            # For xcode 15+ only
            if config.base_configuration_reference && Integer(xcode_base_version) >= 15
                xcconfig_path = config.base_configuration_reference.real_path
                xcconfig = File.read(xcconfig_path)
                xcconfig_mod = xcconfig.gsub(/DT_TOOLCHAIN_DIR/, "TOOLCHAIN_DIR")
                File.open(xcconfig_path, "w") { |file| file << xcconfig_mod }
            end
        end
    end
end

I understand this is a temporary solution. The people who owns these pods are responsible for fixing this permanently.

Updated 11 October 2023 Solutions If you faced this issue after updating to Xcode 15 and can't run your Flutter app on iOS platform.

Solution 1: Update CocoaPods to v1.13 (1.13 released a fix)

It seems to be an issue due to old CocoaPods version with Xcode 15. This is resolved in the CocoaPods version 1.13.0.

You can follow the steps above DT_TOOLCHAIN_DIR cannot be used to evaluate LIBRARY_SEARCH_PATHS, use TOOLCHAIN_DIR instead in xcode 15.

Solution 2: Update Podfile (Flutter / Xcode 15)

However, it's important to note that this should only be used as a temporary solution until a CocoaPods update comes out that fixes your Xcode version.

post_install do |installer|
  installer.pods_project.targets.each do |target|
     flutter_additional_ios_build_settings(target)
      target.build_configurations.each do |config|
        xcconfig_path = config.base_configuration_reference.real_path
        xcconfig = File.read(xcconfig_path)
        xcconfig_mod = xcconfig.gsub(/DT_TOOLCHAIN_DIR/, "TOOLCHAIN_DIR")
        File.open(xcconfig_path, "w") { |file| file << xcconfig_mod }
      end
  end
end

For non-Flutter users: Remove the below line from the script.

flutter_additional_ios_build_settings(target)

Additional fixes related: Update Flutter libraries

If you use inAppWebview, an error like this will appear:

Parse Issue (Xcode): Could not build module 'WebKit'

Update inAppWebview to v5.8.0 release:

flutter_inappwebview: 5.8.0

Look for updates on the libraries you are using within your Flutter project.

Remember after using any of the above solutions

Clean your Flutter project: flutter clean && flutter pub get
Remove Pods directory inside the iOS directory: rm Podfile.lock && rm -rf Pods/
Install and update pods: pod install && pod update
Build and test your app on an iOS device: flutter run. Or build within your Xcode.

Note: "pod update" will update the pod to the latest version possible (as long as it matches the version restrictions in your Podfile), so it is safe to use on Flutter.

It was solved after changing the podfile.

post_install do |installer|
  installer.pods_project.targets.each do |target|
      target.build_configurations.each do |config|
      flutter_additional_ios_build_settings(target)
      xcconfig_path = config.base_configuration_reference.real_path
      xcconfig = File.read(xcconfig_path)
      xcconfig_mod = xcconfig.gsub(/DT_TOOLCHAIN_DIR/, "TOOLCHAIN_DIR")
      File.open(xcconfig_path, "w") { |file| file << xcconfig_mod }
      end
  end
end

In Xcode 15, Apple made a modification to the variable that points to the default toolchain location, replacing $DT_TOOLCHAIN_DIR with $TOOLCHAIN_DIR. If your project or target relies on the previous variable, you should update it to use $TOOLCHAIN_DIR.

To perform this replacement, you can add the following code snippet at the end of your project's Podfile:

post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      xcconfig_path = config.base_configuration_reference.real_path
      xcconfig = File.read(xcconfig_path)
      xcconfig_mod = xcconfig.gsub(/DT_TOOLCHAIN_DIR/, "TOOLCHAIN_DIR")
      File.open(xcconfig_path, "w") { |file| file << xcconfig_mod }
    end
  end
end

After making this change in your Podfile, you will need to install the pods again via the terminal using the command:

pod install

For Flutter developers

To enhance your script's functionality, kindly insert the following line:

flutter_additional_ios_build_settings(target)

Here is the modified script with this addition:

post_install do |installer|
  installer.pods_project.targets.each do |target|
    flutter_additional_ios_build_settings(target)
    target.build_configurations.each do |config|
      xcconfig_path = config.base_configuration_reference.real_path
      xcconfig = File.read(xcconfig_path)
      xcconfig_mod = xcconfig.gsub(/DT_TOOLCHAIN_DIR/, "TOOLCHAIN_DIR")
      File.open(xcconfig_path, "w") { |file| file << xcconfig_mod }
    end
  end
end

This error occurs after updating Xcode to 15 because of some CocoaPods version, so updating it and flushing the caches should solve this problem.

Follow the steps below:

Go to the ios/ folder
```
cd ios
```
Update CocoaPods
```
sudo gem update cocoapods
```
If the above doesn't work, try installing it through Homebrew
```
brew install cocoapods
```
Make sure CocoaPods updated to 1.13.0 or newer version (if available)
```
pod --version
```
Delete the build cache
```
flutter clean
```
Delete the Podfile.lock file
```
rm Podfile.lock
```
Delete the Pods/ folder as well
```
rm -rf Pods/
```
Install the Flutter package dependencies
```
flutter pub get
```
Install the iOS pod dependencies
```
pod install
```
Update your local pods
```
pod update
```

Go to pods → Firebase → Support files, both .release and .debug files.

Change "DT_TOOLCHAIN_DIR" into "TOOLCHAIN_DIR instead". It works for me.

This is due to CocoaPods. Please refer to this comment on the CocoaPods GitHub issue for the fix. It worked for me and many others who were mainly running native iOS projects, but some were also running hybrid projects.

This is happening because of Xcode 15.

I reverted back to Xcode 14.2 or 14.3 by removing the 15 version and downloading the 14.2 xip file, and moved extracted Xcode to "Applications", without opening Xcode and creating Simulator with iOS <16... It worked for me.

Add the below lines to your Podfile and it will fix the issue. It renames all DT_TOOLCHAIN_DIR to TOOLCHAIN_DIR after pods are installed.

post_install do |installer|
  installer.aggregate_targets.each do |target|
    target.xcconfigs.each do |variant, xcconfig|
      xcconfig_path = target.client_root + target.xcconfig_relative_path(variant)
      IO.write(xcconfig_path, IO.read(xcconfig_path).gsub("DT_TOOLCHAIN_DIR", "TOOLCHAIN_DIR"))
    end
  end
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      if config.base_configuration_reference.is_a? Xcodeproj::Project::Object::PBXFileReference
        xcconfig_path = config.base_configuration_reference.real_path
        IO.write(xcconfig_path, IO.read(xcconfig_path).gsub("DT_TOOLCHAIN_DIR", "TOOLCHAIN_DIR"))
      end
    end
  end
