![]() Has this bug been reported to Apple, or is there an alternate way to work with color literals in Xcode 13.2. Instead, the full-blown RGB function appears, in which case it is not possible to bring up the color selection popup to visually select your desired color: If the color literals are arguments in a function call, the little color square doesn't appear anymore. That little color square appears only if I do something like: In addition, its behavior is inconsistent. Now, I have to type "#colorLiteral(" (yes, pound sign, uppercase L, and the left parenthesis) in order for the little color square to appear where I can select my color. There appears to no longer be any shortcut/ autosuggestion for color literal. A small color square would appear where you can visually select your desired color. ![]() As soon as you type "color", the autosuggestion dropdown shows "UIColor Color Literal" and you can simply select it without typing anything more. ![]() You may be wondering, “Why wasn’t overlayBottomRightCoordinate set from the plist?” This isn’t provided in the plist because you can easily calculate it from the other three points.Color Literal used to be recognized in the Xcode IDE. Then the boundary array is set, which you’ll use later to display the park outline. Welcome to Swift / Xcode Trick Level : Beginners XCode 7.1 and Later, Apple introduce File Literal, Color Literal and Image Literal into code file. Then, add this extension after the closing class curly brace:Įxtension ParkMapViewController: MKMapViewDelegate įirst, the park’s coordinates are extracted from the plist file and assigned to properties. You also need to make ParkMapViewController conform to MKMapViewDelegate.įirst, add this import to the top of ParkMapViewController.swift: To set the map view’s delegate, right-click on the map view object to open its context menu and then drag from the delegate outlet to Park Map View Controller like this: In the popup that appears, name the outlet mapView, and click Connect. Then, control-drag from the map view to right above the first method like this: Open ParkMapViewController in the Assistant Editor by holding down the Option key and left-clicking on ParkMapViewController.swift in the file hierarchy. To do anything useful with a MapView, you need to do two things: (1) set an outlet to it, and (2) set its delegate. Next, select the Add New Constraints button, add four constraints with constant 0 and click Add 4 Constraints. Position it below the navigation bar and make it fill the rest of the view. Search for map in the Object Library and then drag and drop a Map View onto this scene. Open Main.storyboard and select the Park Map View Controller scene. You’ll soon add a map and selectable overlay types here. Open the starter project in Xcode build and run and you’ll see a just blank view. This starter includes navigation, but it doesn’t have any maps yet. Getting Startedĭownload the starter project here. ]īy the time you’re done, you’ll have an interactive park map that shows attraction locations, ride routes and character locations. For you fast-ride thrill seekers out there, this app’s for you. ![]() In this MapKit tutorial, you’ll create an app to showcase Six Flags Magic Mountain. Fortunately, you can make maps much more appealing using custom overlay views. The original tutorial was written by Ray Wenderlich.Īpple makes it very easy to add a map to your app using MapKit, but this alone isn’t very engaging. Update note: This tutorial has been updated for Xcode 9, iOS 11 and Swift 4 by Owen Brown. Learn how to add an overlay views using MapKit! ![]()
