How to change minimum OS version?

[ivanperez-keera]

I'm trying to push the Hello example to an iphone running iOS 15.8.

I'm met with the following error message:

Error: StatusError(type: SwiftyMobileDevice.InstallationProxyClient.Error.deviceOsVersionTooLow, name: "DeviceOSVersionTooLow", details: Optional("The system version is lower than the minimum OS version specified for bundle at /var/installd/Library/Caches/com.apple.mobile.installd.staging/temp.nBA5Cj/extracted/Payload/Hello.app. Have 15.8.4; need 17.0"), code: 0)

Is it possible to lower that? I tried modifying xtool/Hello.app/Info.plist:29: <key>MinimumOSVersion</key> but it's reset to 17 immediately when I run xtool dev.

xtool selects the deployment version based on the value in your Package.swift. So you can do something like

let package = Package(
  name: "MyApp",
  platforms: [.iOS(.v15)],
  ...
)
