But that’s fairly easy — a lot of it is just knowing how to translate some syntax. For example, Objective-C “[x doSomething: y]” generally becomes “x.doSomething(y)” in Swift.</div><br class=""><blockquote type="cite" class=""><div class=""><span style="font-family: Alegreya-Regular; font-size: 15px; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px; float: none; display: inline !important;" class="">I’ve done some C, C++, VB 6.0, and VBA / Access in the past but I’m definitely not a programmer.</span></div></blockquote><br class=""></div><div>I’d recommend starting by learning fundamentals, instead of jumping into building an app. Fortunately Xcode’s Playgrounds are a good way to do that, since you can build things like data structures or algorithms interactively. There are a lot of interesting and challenging things you can build that don’t require a fancy GUI but will teach you a lot. For example, look up search trees and see if you can implement various types like binary trees, red/black trees or b-trees. Or implement your own Dictionary class with a hash table.</div><div><br class=""></div><div>—Jens</div></body></html>
