Xcode 8 symbol not found linking sqlite3

I have an project in witch I use 2 pods, a private one that uses SQLCipher, and Google/Analytics that uses the systems sqlite3 (-l"sqlite3").

When I build my project with Xcode 7, everything works correctly, but when I build with Xcode 8 app crashes when trying to open the sqlite db with the following reason:

dlopen(/usr/lib/libsqlite3.dylib, 0x00000001)
dlopen(/usr/lib/libsqlite3.dylib) ==> 0x1feec4f0
dyld: lazy symbol binding failed: Symbol not found: _sqlite3_key
Referenced from: /var/containers/Bundle/Application/524A1D1F-CC6A-4F7C-B86F-CC65EAF17BD5/MyApp.app/MyApp
Expected in: /usr/lib/libsqlite3.dylib

Tested:

|         | iOS 8 | iOS 9 | iOS 10 |
| Xcode 7 |  OK   |  OK   |   OK   |
| Xcode 8 | CRASH | CRASH |    *   |

* app didn't crash but could not open db

What did Xcode 8 change? (https://developer.apple.com/library/content/releasenotes/DeveloperTools/RN-Xcode/Introduction.html)
Any suggestions on how to fix this?

I'm using sqlCipher and I got this problem dyld: lazy symbol binding failed: Symbol not found: _sqlite3_key too. What I do is to add -all_load flag to project Build Settings -> Other Linker Flags, then all works fine. Hope this maybe help to someone. :)

If use pod import, you can add post_install to modify OTHER_LDFLAGS, remove iOS system sqlite3 link flag l"sqlite3".

post_install do |installer|

installer.pods_project.targets.each do |target|
    puts "#{target.name}"    
    target.build_configurations.each do |config|
        xcconfig_path = config.base_configuration_reference.real_path
        puts xcconfig_path

        build_settings = Hash[*File.read(xcconfig_path).lines.map{|x| x.split(/\s*=\s*/, 2)}.flatten]

        if build_settings['OTHER_LDFLAGS']
            other_ldflags = build_settings['OTHER_LDFLAGS']

            puts other_ldflags

            if other_ldflags.include? '-l"sqlite3"'

                puts "find -l sqlite3"

                index = other_ldflags.index('-l"sqlite3"')
                length = '-l"sqlite3"'.length
                first_path = other_ldflags[0,index]
                last_path = other_ldflags[index+length..-1]
                exclude_ldflags = first_path + last_path

                puts exclude_ldflags

                build_settings['OTHER_LDFLAGS'] = exclude_ldflags
            end

            # write build_settings dictionary to xcconfig
            File.open(xcconfig_path, "w")
            build_settings.each do |key,value|
                File.open(xcconfig_path, "a") {|file| file.puts "#{key} = #{value}"}
            end
        end
    end
end

end

Unfortunately, simultaneously using pods dependent on sqlite3 and SQLCipher isn't really a supported scenario with SQLCipher. You might check out this article containing guidance for using SQLCipher with XCode 8 for reference, but what you are trying to do is high risk.
