Deployment target build warning in Xcode 12+ when installing via Cocopods

[adamjansch]

Since updating to Xcode 12, many Pods (including MIKMIDI) are creating this build warning:

The iOS Simulator deployment target 'IPHONEOS_DEPLOYMENT_TARGET' is set to 8.0, but the range of supported deployment target versions is 9.0 to 14.0.99.

The solution (as mentioned in CocoaPods/CocoaPods#9884) is to raise the minimum deployment target in the podspec.

Considering this would change the compatibility range of MIKMIDI would this solution be acceptable?

Hi @aj-bmdi, this change has already been made on the 1.8 branch. I need to finish up some work before releasing that, but will do so fairly soon. In the meantime, you can workaround this by either switching your Podfile to point to that branch, or adding the following to the bottom of your Podfile:

post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '12.0'
    end
  end
end

Replace 12.0 with your project's actually target. You could also potentially modify that to only change MIKMIDI's deployment target, but if your experience is like mine, it won't be the only pod for which that's needed...

Awesome, thanks for the info!
