SwiftUI Series 03｜Troubleshooting common layout problems when the page “looks a bit bad”

Many issues with SwiftUI pages are subtle:

• Call it wrong, it’s not obviously broken.
• Let’s just say it’s true. It looks a little bit worse.

Common feelings include:

• The card seems a bit floaty
• There is a strange relationship between text and icons
• Spacing looks unstable
• Certain areas always look crowded or empty

This type of problem is most likely to be mistaken for “insufficient aesthetics” or “the design feels wrong.” But many times, it’s still essentially a layout issue, just:

Are the structure, space allocation and visual rhythm aligned on the same level?

1. Many pages that “look a little bad” are actually because the main structure is not stable.

The reason why some pages always look awkward is that on the surface it seems like a certain padding is missing, but actually closer to the main structure itself it is a bit blurry.

For example, if a card block is also responsible for:

• Content main axis layout
• local alignment
• Decorative layering
• Spacing fix

In the end it is very easy to become:

• can be displayed logically
• It’s always a bit visually scattered

The reason is simple: When a layout layer is responsible for too many things, local fine-tuning will continue to affect the overall structure.

2. The most common problem is that hierarchical responsibilities are mixed.

Many pages might look like this:

• Outer layer VStack
• The middle ones HStack
• Add padding to each layer
• Mix some more Spacer
• In the end, if you don’t like it, add another frame

The problem with this way of writing is not necessarily wrong, but rather unclear hierarchical responsibilities. It’s hard to tell:

• Which layer is responsible for content structure
• Which layer is responsible for local alignment -Which layer is just visual decoration

Once these things are mixed in the same layer, the page can easily enter a state: Every tweak looks reasonable, but the whole thing is getting harder and harder to stabilize.

3. Visually “unstable” pages are often caused by unstable spacing systems.

This is a very high frequency problem.

Many pages don’t look high-end. On the surface, they look like colors or fonts, but in fact they are closer to inconsistent spacing and rhythm:

• 12 between A and B
• between B and C 18
• Between C and D it becomes 14 again

If these differences do not have clear semantics and are just made up as you write, the page will lack a sense of rhythm.

So for many pages that “look bad”, what you really need to check is not:

• Is there still a divider missing here?

Instead:

• Whether the vertical rhythm between information blocks of the same type is consistent
• Is there a stable hierarchy between the main title, subtitle, and explanatory text?
• Whether the inner and outer margins of the card follow the same set of dimensions

SwiftUI makes it easy for people to quickly build a structure, but without a stable spatial rhythm, the page will always be in a state of “the function is right, but the temperament is wrong”.

4. Text often makes the page “worse”

Because text is the element that most easily exposes whether the layout logic is stable.

Frequently asked questions include:

• If the title is too long, it will distort the overall structure.
• The subtitle is unbalanced after line wrapping
• Unnatural baseline relationship between icon and text
• The width control of different text blocks is inconsistent

These issues are usually not decided in advance:

• Who has higher text priority?
• How wide should the text be?
• Whether the layout is still stable when there are multiple rows

Once a page looks normal only under “short copy conditions”, the real content will be revealed as soon as it comes in.

5. The more the tune becomes, the more chaotic it becomes.

Because they deal with “appearances”, not “structural causes”.

For example, when something on the page doesn’t satisfy your eyes, it’s easy to instinctively:

• Add another padding
• Add another Spacer
• Set another frame

Of course it may be more pleasing to the eye in the short term, but if you don’t look back and ask:

• Which floor should be responsible for space allocation here?
• Is this repair just wiping out structural problems?

In the future, we will often rely more and more on local patches instead of the structure itself.

The reason why SwiftUI pages are easy to “get weirder as they change” is largely because it makes local modifications particularly easy.

6. A more effective troubleshooting sequence

If a SwiftUI page “looks bad”, I usually check in this order:

1. Whether the main structural layer is clear.
2. Whether the spacing between information blocks at the same level is uniform.
3. Is the text stable in long content, short content, and multiple lines?
4. Which modifiers are structural and which are just post-patches.
5. Whether a local correction is disrupting the overall rhythm.

This order has advantages: It’s asking “Which level of responsibility has been mixed up?”

7. Conclusion: Many pages are “not advanced” because the layout level and rhythm are not unified.

To put it in shorter form, I would say:

SwiftUI pages always “look a little worse”, and often appear to be incompetent in writing interfaces. In fact, the layout level, space allocation and visual rhythm are not treated as a system.

Therefore, the most effective method of reform is usually to look back and review:

• Is the main structure standing?
• Whether the spacing has a consistent rhythm
• Whether text and content remain stable under real data

Once these three things become clear, the page temperament usually improves significantly.
