Xcode - Our Experience

When using Xcode for the first time it can be a bit tricky. So here's some useful things that we have found out along the way when developing using Swift in Xcode 6.

Zooming

• In iOS Simulator:
• ⌘+1 for 100%
• ⌘+2 for 75%
• ⌘+3 for 50%
• In storyboard:
• Double click outside of view will toggle between zoomed in and zoomed out
• There is a keyboard shortcut but it's less efficient

Adding tab to tabbed application

• Add a view controller from the object library to the storyboard
• Find the Tab Bar Item from the object library and add it to your new view controller
• Select the Tab Bar Controller and hold down control and drag onto the new view controller
• Select view controllers under relationship segue

Custom tab bar items

• Click on the Images.xcassets folder
• Right click and select import and navigate to the appropriate item
• Go to the storyboard and click on the tab bar item you want to give a custom item
• Set the image and title

Adding layout constraints

• Go to the storyboard
• From the hierarchy of scenes:
• Hold down control and click on the view that will constrain your view, i.e. to have a table view take up the entire view for different resolutions you would select the parent view
• Drag down and select the view you want to constrain
• Select the constraint type

Adding duplicate component

Hold down alt key and drag on existing component
