Firebase iOS Version breakdown
// How to:
// 1. Open the Firebase Analytics Dashboard
// 2. Scroll to bottom, where you see the "Users by Device model" widget
// 3. Click "View device models" in that widget (this opens the "Tech details" Firebase Analytics page)
// 4. Above the table shown in the new page, click on the “Device model” drop down menu and select “OS with Version”
// 5. Make sure to select “OS with version” and not “OS Version”
// 6. On the top right corner of the page, click on the “Share this report” icon (next to the date)
// 7. Click “Download file” on the new side bar, then “Download CSV"
// 8. Open the file and select the iOS/Android breakdown raw data
// 9. Replace the sample data in this script with your data
# When I want to attach lldb to swiftc to see how it works when compiling simple Swift programs:

--release --debug-swift \
--build-swift-dynamic-stdlib=0 --build-swift-dynamic-sdk-overlay=0 \
--skip-build-osx --skip-build-ios --skip-build-tvos --skip-build-watchos
# When I want to run the Swift test suite, to make sure my pull request would pass CI:
utils/build-script \
--release --debug-swift \
--test

An Objective-C PSD writer that got shelved. Nick Paulson and Gus Mueller helped me out with this.

@interface FOOPSDWriter : NSObject {
NSMutableData *data_;

Adding methods to NSData and NSString using categories to provide AES256 encryption on iOS

Important notice

I took down this Gist due to concerns about the security of the encryption/decryption part of this code (see comments below).

Rob Napier (@rnapier) has created a publicly available class that provides similar AES encryption/decryption functionality at https://github.com/rnapier/RNCryptor.
