Xcode 12 Workaround

[tattn]

I use Carthage to build SwiftyJSON.
But it was failed in Xcode 12 beta 1.

Show the following error:

Undefined symbols for architecture armv7:
  "type metadata for Swift._StringObject.Variant", referenced from:
      outlined init with take of Swift._StringObject.Variant in SwiftyJSON.o
ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)

It can be also reproduced on archive build.

So I added the workaround for Xcode 12.
Please try the following if you use Carthage:

github "tattn/SwiftyJSON" "hotfix-xcode12"

The change is https://github.com/SwiftyJSON/SwiftyJSON/compare/master...tattn:hotfix-xcode12?expand=1.

I think the type inference of String may be broken in Xcode 12 beta 1.

For CocoaPods you can temporarily use
pod 'SwiftyJSON', :git => 'https://github.com/tattn/SwiftyJSON.git', :branch => 'hotfix-xcode12'

Looks like it is still broken in Xcode beta 2. 😢

This is fixed on beta 4

It throws No such module 'SwiftyJSON' I'm using: pod 'SwiftyJSON', '~> 5.0' (XCode 12, it was working fine on XCode 11)
Any ideas?

This fix won't work on Xcode 12.2. SwiftyJSON is still throwing 'no such module'
