Sometimes you just want to print a message that tells you a line of code was executed. Inspired by a tweet from Paige Sun:
View logMilestone.swift
/// Log the current filename and function, with an optional extra message. Call this with no arguments to simply print the current file and function. Log messages will include an Emoji selected from a list in the function, based on the hash of the filename, to make it easier to see which file a message comes from.
/// - Parameter message: Optional message to include
/// - file: Don't use; Swift will fill in the file name
/// - function: Don't use, Swift will fill in the function name
/// - line: Don't use, Swift will fill in the line number
func logMilestone(_ message: String? = nil, file: String = #file, function: String = #function, line: Int = #line) -> Void {
// Feel free to change the list of Emojis, but don't make it shorter, because a longer list is better.

A wrapper around SecCertificate to simplify accessing iOS app certificate properties found in the embedded.mobileprovision file inside the bundle payload. The WrapperImplementation file shows how to extract both the provisioning profile and the details of each certificate. Works on iOS 12, iOS 13, and newer
View SecCertificateWrapper.swift
struct SecCertificateWrapper : Comparable {
var data:Data
var cert:SecCertificate
// Initialize with a data object from the "DeveloperCertificates"
// array (see WrapperImplementation.swift)
init(data:Data) {
self.cert = SecCertificateCreateWithData(nil, data as CFData)!
// Use this later for parsing the date details from the cert
