The Correct Way To Download Ios Runtime

the general workflow is to download ios runtime in xcode, but xcode shouted download is failed

this is not only for me, lots of developers reported this issue, I think it's Apple's fault.

then we have to download it manually.

go to https://developer.apple.com/download/all/?q=Xcode to download ios runtime you like.

tips for Chinese developers, you need a 🪜 for normal access

After your dmg file is downloaded, then go to your shell,

bash
# tell which xcode to load you ios, mine is at default path
sudo xcode-select -s /Applications/Xcode.app
xcodebuild -runFirstLaunch
xcrun simctl runtime add "~/Downloads/<somewhat.dmg>"

the forgoing is what Apple doc told you, but what it hasn't told you is:

bash
Accessing '/Users/<Username>/Downloads/<somewhat.dmg>' requires Security & Privacy approval.

since terminal cannot add files to disk by default,

you should go to your mac settings, Security & Privacy > Full disk access > Give terminal full permission

run those bash commands again,

bash
D: 134B74D0-63F2-43ED-9E2B-21B5739CA8A5 iOS (18.2 - 22C150) (Ready)
# if this pops up means you are okay

Then you can play iphone 16 in your mac!
