Xcode 9 - No option to create dylib project iOS

I remember in old Xcode there was option under Create New Project there was option to create BSD Dynamic Library - dylib. However now I see only Cocoa Framework, Static Library and Metal Library.

Any hints?

You may create a project for an iOS static lib, and create a dynamic lib from the static one with a custom build phase with the following command:

xcrun --sdk iphoneos clang -arch <ARCH> -shared -all_load \
    -o lib<NAME>.dylib lib<NAME>.a

where <ARCH> is either armv7 or arm64 and <NAME>is the base name of your lib. You may check or list the architectures with file command. E.g.:

file <path>/lib<NAME>.a`
lib<NAME>.a (for architecture armv7):   current ar archive random library
lib<NAME>.a (for architecture arm64):   current ar archive random library

If more than one architecture is listed, Xcode has produced a universal static library. In this case you may create a universal shared library with multiple -arch flags: 

xcrun --sdk iphoneos clang -arch armv7 -arch arm64 -shared -all_load \
    -o lib<NAME>.dylib lib<NAME>.a

You may need to specify additional linker flags (e.g. -l for linking non-standard libs).
