the Brush Tracker app in 3 days with no prior expertise with Swift, the primary programming language for iOS improvement. Though I’ve a totally practical app dwell on the App Retailer, I nonetheless have little or no Swift information as a result of I used “vibe coding” to develop this app.
On this article, I’ll clarify the method, AI instruments I used, and share a few of my learnings and insights.
Something as Lovable different
I beforehand used Lovable for creating internet purposes however it doesn’t appear to be an choice for cellular app improvement, a minimum of for now.
There are options to Lovable for app improvement. I not too long ago got here throughout a device known as Something, and since I’d had such a superb expertise with Lovable, I made a decision to provide it a attempt to develop my app. At first, it appeared to work nicely, however the total expertise wasn’t as environment friendly as I’d hoped.
The toughest half was not having the ability to take a look at my modifications, fixes, and enhancements instantly. Something does have a built-in UI for testing, however the expertise wasn’t very easy. It additionally directs you to check the code by the Expo app, however that didn’t work nicely for me both.
I ought to point out that I didn’t have any prior app improvement expertise. For builders or anybody with some coding background, Something might most likely be a extra productive device than it was for me.
I exported the code from Something and tried to check it on Xcode on my mac however obtained many errors and couldn’t get it to working. So I made a decision to make use of an alternate. Cursor appeared to the plain selection.
Cursor
I’ve heard superb issues about Cursor from many mates who’re actively utilizing it. I wished to provide it a strive myself.
I used the identical immediate in Cursor and requested it to construct the app. Then I created an XCode undertaking with the folders and recordsdata generated by Cursor. I began the simulator on XCode and it labored on the primary strive.
The objective of Brush Tracker is that will help you keep constant along with your each day toothbrushing. It offers you a cleanliness rating that begins at 100%. For those who skip a day, the rating drops and your tooth within the app begin to look a bit yellowish to match the cleanliness rating.
Notice: All pictures used on this article embody screenshots from my app, Brush Tracker.
The primary model solely had the primary characteristic of the app. I believe that is probably the most environment friendly manner of constructing merchandise with AI-based instruments. Get the primary model up and operating earlier than including options.
To check the app’s core characteristic on the simulator, I needed to change the simulator’s date with out finishing “immediately’s brushing” to test whether or not the cleanliness rating would drop and the tooth visualizations would replace as anticipated.
Cursor instructed to vary the date on the XCode simulator however the simulator doesn’t have the date and time settings anymore. Older variations of XCode simulator had this setting however not anymore.
A workaround resolution was to vary the date on my Mac. This manner, the date on the simulator additionally modified and I used to be capable of take a look at the characteristic.
One factor I seen was that once I modified the date on my Mac, Cursor didn’t see my account and didn’t work. It obtained again to regular once I modified the date again to auto.
Timer characteristic
A built-in brushing timer felt like the nice addition to Brush Tracker. Customers can merely mark a brushing session as completed or use the timer whereas they brush.
It took me just a few tries to get this characteristic working the way in which I imagined. You may simply inform Cursor so as to add a characteristic, however it works a lot better if you tweak the immediate and clarify precisely what you need. When you give clear directions, Cursor often does an ideal job.
Reward characteristic
I wished so as to add an additional motivation when the consumer completes each day brushings. After finishing the periods, they will faucet “Get Your Each day Reward” and see a brief motivational quote. It’s a small contact however a pleasant reminder for dental well being.
You may truly be taught whereas vibe coding
Cursor not solely writes the code but in addition helps you be taught. Once I was attempting so as to add the reward characteristic, the implementation was not right at first. It wasn’t working correctly.
I described the problem to Cursor, and it defined each what was the reason for the issue and the way to repair it. Listed below are two examples of how Cursor may also help you be taught alongside the way in which:
The problem is that rewardQuote is empty on the primary faucet as a result of handleRewardTap() units it, however the sheet is offered instantly. I want to make sure the quote is about earlier than displaying the sheet.
Fastened the problem! The issue was that showReward = true was being set instantly after rewardQuote, however SwiftUI’s sheet presentation can occur earlier than the state replace is totally processed.
Use Cursor extra effectively
Cursor is a superb device however there are some methods to make it extra environment friendly.
Let’s assume code fails or it doesn’t execute appropriately. If the problematic half, spotlight that part and add to the chat. It undoubtedly makes it simpler for Cursor to repair drawback.
In Brush Tracker, I used to be having an issue when organising notifications. I outlined the issue and requested Cursor to repair it. Cursor instructed me it was mounted however the issue nonetheless existed. Then, from the code modifications I discovered the place the issue was occurring and added that half to the chat.
Cursor mounted it on the subsequent strive: The issue is that the onTapGesture is utilized to the Picker, however in SwiftUI, segmented pickers don’t at all times reply nicely to faucet gestures as a result of they’ve their very own inside gesture dealing with. The onChange modifier solely triggers when the choice truly modifications, not when the identical worth is tapped.
One other factor price mentioning is the “context used” share in Cursor. It robotically captures related context out of your codebase, so that you don’t have to inform it which recordsdata to take a look at. However your chat historical past can be included in that context, and generally it incorporates previous issues or irrelevant code.
That further litter can enhance token utilization or make Cursor much less environment friendly. When the context used share will increase, I clear the chat historical past.
Distributing your app within the App Retailer
When you full testing your app utilizing the simulator or a bodily gadget (e.g. your personal iPhone), it’s time to distribute your app within the App Retailer in order that others can see (and hopefully use) your app.
It’s not an advanced course of however there are a whole lot of particulars, which could take lengthy particularly if you’re doing it for the primary time. I discovered a video on YouTube that clearly explains your complete course of step-by-step.
After finishing all of the steps, I submitted my app for evaluation. As soon as it was accepted, I obtained an e mail from App Retailer Join letting me comprehend it was prepared for distribution.
I’d prefer to level out that I don’t have any affiliation with any of the AI instruments talked about on this article.
Thanks for studying! You may try Brush Tracker on the App Retailer. I’d love to listen to from you should you strive it or have any suggestions.
