Open Xcode Live Preview for UIKit

Mac OS Swift

One of the big benefits of using SwiftUI is that you can hot update the App like Flutter，UI code changed，Will be directly reflected in the simulator or the real machine，Greatly improve the efficiency of writing user interfaces，No need to change 1px，run，Various clicks，Then check the loop of effects。But it's too early to use SwiftUI，After all, there is still a lot of iOS 12 Equipment is running，Want to do popular software，That still needs to be supported。

Then，Is there any way to make UIKit The software written can also be used in real-time[……]

Run and train Moses on macOS

Mac OS

Moses official website actually has macOS Binary packageof，You don't need to compile them from source。But in short,，Since Moses developers no longer use Macs，So he can't update，This leads to a bug in the code of the latest version (4.0)，Make the binary file can not be used directly，The author said, "It's not difficult to compile from source anyway..." But in short，It is almost impossible to compile Moses from BigSur，Various strange errors，Headache。

Mac OS
Use advanced settings to modify Packages default parameters

Until some users say that although the app supports the m1 chip，But the installation package does not work-when running the pkg installation package，Rosetta 2 pops up...

Although it does not affect[……]

macOS uses the atos command to parse arbitrary crash records and sample data

Mac OS Swift

Recently, the drop grid input method has encountered several difficult to reproduce problems-the key is that it will not cause a crash。This makes the crash statistics function completely ineffective，The specific performance is that the input method will suddenly get stuck for a few seconds in some cases，Very annoying。Then I thought，macOS comes with activity manager，There is a "sampling" function，You can see the current execution (call) status of the corresponding process，Can I use it to analyze the cause of the error?

After communicating with users，I got a sampling report like this：

Use a third-party mouse without a driver on macOS

Mac OS Exchange of Experience
Enable management of Logitech mouse

All to known，macOS to third partiesmouseVery picky，If it is an ordinary office mouse，That almost works，At most, the fixed DPI requires adjusting the mouse speed.，But if it goes up to a gaming mouse with more buttons，There are many problems。

Use xcodebuild to archive and export app

Mac OS

I wrote an article beforemacOS app script to automate notarize，But there is no mention of using code to automatically compile and generate App scripts，After all, there are many tools to complete this step，For example, fastlane。

I didn’t think about automation before notarize，At the time of writing that article, fastlane did not support notarized upload，So I wrote it myself，The specific compilation command is like this：
