Swindler does not compile on Xcode 10.2 #57

Closed thieso2 closed 5 years ago

The new compiler seems more picky. I would try to fix it myself and my Swift Kung-Fu is not yet strong enough to see the fixes immediately. I tried setting the SWIFT_VERSION to 4.x, it does not help. Once you have upgraded to Xcode 10.2 you cannot compile Swindler any more.

I have attached the output of:

xcodebuild -workspace "Swindler.xcworkspace" -scheme "Swindler" | xcpretty

Mostly it complains about "parameter ... could not be inferred".

Same issue.

This looks like it will take some time to get to the bottom of. The way Swift type constraints / inference has worked since the beginning of the project just changed in a minor version of Xcode.

I'll need to set aside some time to minimize the errors down to a smaller example so I can play with it and understand what's going on. If anyone is interested in doing the minimization part of this, feel free, otherwise I'll get to it when I can set aside a few hours to work on this.
