background:
A student who was engaged in IOS development switched from Tencent to Kuaishou, which made me want to try IOS development on a whim.
Naturally everything starts with Hello Word.
Time: April 3, 2020
Introduce my computer configuration:
The first step is to download and install XCode (app store does not support, manual installation is required)
I walked into the APP store naturally
But I found that my Mac OS does not support it. This is also the first time I failed to install in the APP store.
Go to:
https://developer.apple.com/download/more/
A suitable version was found. (Actually, I don’t know which version can be adapted to which Mac OS, it is completely installed and found to work)
The second step, open -> create -> run
Select Create a new Xcode project in the image above
Enter key information
After the creation is successful, there will be some code interface.
Then find the arrow and run.
Run successfully. The road is long and long, slowly exploring.
