Genau, wie @ChrisBtt sagt wird durch so eine Unwind Segue einfach der Punkt in der View Controller Hierarchie definiert, zu der die Segue zurückkehrt. Das passiert dann automatisch. Du musst nur eine Verbindung zur Exit Schaltfläche ziehen und der Segue dann einen identifier geben:

Dann kannst du in unwindToCanvas und prepareForSegue je nach identifier entscheiden, was zu tun ist.

// TODO: For the "selectedAccessory" segue, obtain the selected accessory and add it to the canvas.
