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

- Select view controllers under relationship segue

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
