I have the same issue, apple silicon mac seems can not run iOS apps at landscape mode..

One of your dependency has UIDeviceFamily ['3', '5'] in it's Info.plist, remove '5' from the Info.plist can solve this issue. More debug info: modify /Applications/Xcode.app/Contents/Developer/usr/bin/ipatool add below line (line 1599) can help print out which dependency libraries has incorrect ['3', '5'] in it's Info.plist 1595	 def supportedIdioms 1596		 if not defined? @supportedIdioms 1597			 @supportedIdioms = lambda { 1598				 family = infoDict["UIDeviceFamily"] 1599				 $stderr.puts "debug family '#{family}' '#{infoDict}'"
